Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?Group of answer choicesBitsFramePacketSegment

The Protocol Data Unit (PDU) that is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model is a Segment.

Here are the steps of how it works:

1. When a host computer receives a message, it starts the de-encapsulation process at the physical layer of the TCP/IP model. Here, the PDU is Bits.

2. The host computer then moves to the data link layer, where the PDU is a Frame.

3. Next, the host computer de-encapsulates the message at the network layer. Here, the PDU is a Packet.

4. Finally, the host computer de-encapsulates the message at the transport layer. At this layer, the PDU is a Segment.

So, the answer to your question is Segment.

The Protocol Data Unit (PDU) that is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model is a Segment.

Here's a step-by-step explanation:

1. When data is sent over the internet, it is divided into smaller units for efficient transmission. These units are called Protocol Data Units (PDUs).

2. Each layer of the TCP/IP model has a different name for its PDU. For instance, the Network Interface layer's PDU is called a Frame, the Internet layer's PDU is called a Packet, and the Transport layer's PDU is called a Segment.

3. De-encapsulation is the process of removing headers from data as it moves up the layers in the TCP/IP model.

4. When a host computer receives data, it starts de-encapsulating the message at the Network Interface layer by converting the Frame into a Packet.

5. The Packet is then passed to the Internet layer, where it is further de-encapsulated into a Segment.

6. Therefore, at the Transport layer, the PDU being processed (i.e., de-encapsulated) is a Segment.
